The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas-fir.
Pseudotsuga menziesii var. glauca, or Rocky Mountain Douglas-fir, is an evergreen conifer native to the interior mountainous regions of western North America, from central British Columbia and southwest Alberta in Canada southward through the United States to the far north of Mexico. The range is continuous in the northern Rocky Mountains south to eastern Washington, eastern Oregon, Idaho, western and south-central Montana and western Wyoming, but becomes discontinuous further south, confined to "sky islands" on the higher mountains in Utah, Colorado, Arizona and New Mexico, with only very isolated small populations in eastern Nevada, westernmost Texas, and northern Mexico. It occurs from 600 m altitude in the north of the range, up to 3,000 m, rarely 3,200 m, in the south. Further west towards the Pacific coast, it is replaced by the related coast Douglas-fir, and to the south, it is replaced by Mexican Douglas-fir in high mountains as far south as Oaxaca. Some botanists have grouped Mexican Douglas-fir with P. menziesii var. glauca, but genetic and morphological evidence suggest that Mexican populations should be considered a different variety.
Alnus rubra, the red alder, is a deciduous broadleaf tree native to western North America.
Thuja plicata is a large evergreen coniferous tree in the family Cupressaceae, native to the Pacific Northwest of North America. Its common name is western redcedar in the U.S. or western red cedar in the UK, and it is also called pacific red cedar, giant arborvitae, western arborvitae, just cedar, giant cedar, or shinglewood. It is not a true cedar of the genus Cedrus. T. plicata is the largest species in the genus Thuja, growing up to 70 metres (230 ft) tall and 7 m (23 ft) in diameter. It mostly grows in areas that experience a mild climate with plentiful rainfall, although it is sometimes present in drier areas on sites where water is available year-round, such as wet valley bottoms and mountain streamsides. The species is shade-tolerant and able to establish in forest understories and is thus considered a climax species. It is a very long-lived tree, with some specimens reaching ages of well over 1,000 years.
The Pacific temperate rainforests of western North America is the largest temperate rain forest region on the planet as defined by the World Wildlife Fund. The Pacific temperate rainforests lie along the western side of the Pacific Coast Ranges along the Pacific Northwest Coast of North America from the Prince William Sound in Alaska through the British Columbia Coast to Northern California, and are part of the Nearctic realm, as also defined by the World Wildlife Fund. The Pacific temperate rain forests are characterized by a high amount of rainfall, in some areas more than 300 cm (10 ft) per year and moderate temperatures in both the summer and winter months.
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests, it is used by foresters to create certain types of forest ecosystems and to promote select species that require an abundance of sunlight or grow in large, even-age stands. Logging companies and forest-worker unions in some countries support the practice for scientific, safety and economic reasons, while detractors consider it a form of deforestation that destroys natural habitats and contributes to climate change. Environmentalists, traditional owners, local residents and others have regularly campaigned against clearcutting, including through the use of blockades and nonviolent direct action.
The Douglas Ranges are a subrange of the Pacific Ranges of the Coast Mountains of the Canadian province of British Columbia, about 70 km (43 mi) east of downtown Vancouver, north of the Fraser River and between the valleys of Stave and Harrison Lakes. They are approximately 4,900 km2 (1,900 sq mi) in area. Their highest peak is Mount Robertson 2,252 m (7,388 ft), at the northwest limit of the range.
Carmanah Walbran Provincial Park, originally Carmanah Pacific Provincial Park, is a remote wilderness park located inside traditional Ditidaht First Nation ancestral territory. The park covers a land area of 16,450 ha (63.5 sq mi) immediately adjacent to Pacific Rim National Park Reserve's West Coast Trail on the south-western, coastal terrain of Vancouver Island. The provincial park comprises the entire drainage of Carmanah Creek, and a good portion of the lower Walbran River drainage, both of which independently empty into the Pacific Ocean. The park is named after the Anglicized diitiid?aatx word kwaabaaduw7aa7tx, or Carmanah, meaning "thus far upstream" and John Thomas Walbran, a colonial explorer and ship's captain. Access to the park is by gravel logging road from Port Alberni, Lake Cowichan, or Port Renfrew.
ȽÁU,WELṈEW̱/John Dean Provincial Park, formerly John Dean Provincial Park, is a small, densely vegetated provincial park on the Saanich Peninsula of southern Vancouver Island, British Columbia, Canada. The park is located on and around ȽÁU,WELṈEW̱, a small mountain in the traditional territory of Wsanec First Nations, itself situated 20 km north of Victoria, the provincial capital city.
MacMillan Provincial Park is a 301-hectare (740-acre) provincial park in British Columbia, Canada. Located 25 km (16 mi) west of Qualicum Beach and 16 km (9.9 mi) east of Port Alberni, the park straddles Highway 4 and the Island Rail Corridor in central Vancouver Island. It is nestled on the western shore of Cameron Lake, and protects the delta of the Cameron River. The park is home to a famous, 157-hectare (390-acre) stand of ancient Douglas fir, known as Cathedral Grove, which draws visitors from all over the world. The park provides the only highway-accessible protected old-growth Douglas-fir forest in British Columbia. In 2007 Cathedral Grove made the short list on CBC's competition Seven Wonders of Canada.
The Opal Creek Wilderness is a wilderness area located in the Willamette National Forest in the U.S. state of Oregon, on the border of the Mount Hood National Forest. It has the largest uncut watershed in Oregon.
The Boole Tree is a giant sequoia in the Giant Sequoia National Monument, Fresno County, California. The Boole Tree is the eighth tallest sequoia in the world and is the largest in terms of base circumference at 113 feet. It is estimated to be more than 2,000 years old. The tree's stature is accentuated by its isolation above the Kings River where it towers over the rest of the forest.
The Ancient Forest Alliance is a grassroots environmental organization in British Columbia, Canada. It was founded in January 2010, and is dedicated to protecting British Columbia's old-growth forests in areas where they are scarce, and ensuring sustainable forestry jobs in that province.
Pseudotsuga menziesii var. menziesii, commonly known as Coast Douglas-fir, Pacific Douglas-fir, Oregon pine, or Douglas spruce, is an evergreen conifer native to western North America from west-central British Columbia, Canada southward to central California, United States. In Oregon and Washington its range is continuous from the Cascades crest west to the Pacific Coast Ranges and Pacific Ocean. In California, it is found in the Klamath and California Coast Ranges as far south as the Santa Lucia Mountains with a small stand as far south as the Purisima Hills, Santa Barbara County. In the Sierra Nevada it ranges as far south as the Yosemite region. It occurs from near sea level along the coast to 1,800 metres (5,900 ft) in the California Mountains. Further inland, coast Douglas-fir is replaced by Rocky Mountain or interior Douglas-fir. Interior Douglas-fir intergrades with coast Douglas-fir in the Cascades of northern Washington and southern British Columbia.
